DETAILED DESCRIPTION

Example embodiments will now be described more fully hereinafter with reference to the accompanying drawings; however, they may be embodied in different forms and should not be construed as limited to the embodiments set forth herein.  Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey exemplary implementations to those skilled in the art.

In the drawing figures, the dimensions of layers and regions may be exaggerated for clarity of illustration. It will also be understood that when a layer or element is referred to as being “on” another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. Further, it will be understood that when a layer is referred to as being “under” another layer, it can be directly under, and one or more intervening layers may also be present. In addition, it will also be understood that when a layer is referred to as being “between” two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present. Like reference numerals refer to like elements throughout.

The terms or words used in this specification and claims should not be construed as being limited to the usual or dictionary meaning and should be interpreted as meaning and concept consistent with the technical idea of the present disclosure based on the principle that the inventor can be his/her own lexicographer to appropriately define the concept of the term.

The embodiments described in this specification and the configurations shown in the drawings are provided as some example embodiments of the present disclosure and do not represent all of the technical ideas, aspects, and features of the present disclosure. Accordingly, it is to be understood that there may be various equivalents and modifications that may replace or modify the embodiments described herein at the time of filing this application.

It is to be understood that when an element or layer is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it may be directly on, connected, or coupled to the other element or layer or one or more intervening elements or layers may also be present. When an element or layer is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. For example, when a first element is described as being “coupled” or “connected” to a second element, the first element may be directly coupled or connected to the second element or the first element may be indirectly coupled or connected to the second element via one or more intervening elements.

As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Further, the use of “may” when describing embodiments of the present disclosure relates to “one or more embodiments of the present disclosure. Expressions, such as “at least one of” and “any one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. When phrases such as “at least one of A, B, and C,” “at least one of A, B, or C,” “at least one selected from a group of A, B, and C,” or “at least one selected from among A, B, and C” are used to designate a list of elements A, B, and C, the phrase may refer to any and all suitable combinations or a subset of A, B, and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively. As used herein, the terms “substantially,” “about,” and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent variations in measured or calculated values that would be recognized by those of ordinary skill in the art.

It is to be understood that, although the terms “first,” “second,” “third,” etc. may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It is to be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” or “over” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

The terminology used herein is for the purpose of describing embodiments of the present disclosure and is not intended to be limiting of the present disclosure. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It is to be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Also, any numerical range disclosed and/or recited herein is intended to include all sub-ranges of the same numerical precision subsumed within the recited range. For example, a range of “1.0 to 10.0” is intended to include all subranges between (and including) the recited minimum value of 1.0 and the recited maximum value of 10.0, that is, having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limitation recited herein is intended to include all lower numerical limitations subsumed therein, and any minimum numerical limitation recited in this specification is intended to include all higher numerical limitations subsumed therein. Accordingly, Applicant reserves the right to amend this specification, including the claims, to expressly recite any sub-range subsumed within the ranges expressly recited herein.

References to two compared elements, features, etc. as being “the same” may mean that they are “substantially the same. Thus, the phrase “substantially the same” may include a case having a deviation that is considered low in the art, for example, a deviation of 5% or less. In addition, when a certain parameter is referred to as being uniform in a given region, it may mean that it is uniform in terms of an average.

Throughout the specification, unless otherwise stated, each element may be singular or plural.

When an arbitrary element is referred to as being disposed (or located or positioned) on the “above (or below)” or “on (or under)” a component, it may mean that the arbitrary element is placed in contact with the upper (or lower) surface of the component and may also mean that another component may be interposed between the component and any arbitrary element disposed (or located or positioned) on (or under) the component.

In addition, it is to be understood that when an element is referred to as being “coupled,” “linked,” or “connected” to another element, the elements may be directly “coupled,” “linked,” or “connected” to each other, or one or more intervening elements may be present therebetween, through which the element may be “coupled,” “linked,” or “connected” to another element. In addition, when a part is referred to as being “electrically coupled” to another part, the part may be directly electrically connected to another part or one or more intervening parts may be present therebetween such that the part and the another part are indirectly electrically connected to each other.

Throughout the specification, when “A and/or B” is stated, it means A, B, or A and B, unless otherwise stated. That is, “and/or” includes any or all combinations of a plurality of items enumerated. When “C to D” is stated, it means C or more and D or less, unless otherwise specified.

Hereinafter, a detailed configuration of the management module 3 will be described.

The sensing module 31 may include a sensing module body 310, a sensing part 311, and a sensing pad portion 312.

The sensing module body 310 may be provided as a flexible printed circuit board (FPCB). As described above, as the sensing module body 310 is provided as the FPCB, a shape of the sensing module body 310 may be relatively freely changed.

The sensing module body 310 may be disposed on the busbar holder 33. According to one or more embodiments, the sensing module body 310 may be disposed on the busbar holder 33. The sensing module body 310 may be disposed on the busbar holder 33 and connected to the battery cell 2.

The communication pad portion 321 may be disposed on the communication module body 320 and be in contact with the sensing pad portion 312 of the sensing module body 310. According to one or more embodiments, the communication pad portion 321 may be on a lower portion of the communication module body 320.

As the communication pad portion 321 is in contact with and electrically connected to the sensing pad portion 312, the communication module 32 may receive a signal from the sensing module 31. The signal transmitted to the communication module 32 from the sensing module 31 may include operation information and state information of the battery cell 2 and/or the busbar holder 33.

The communication module element 322 may be disposed on the communication module body 320.

Accordingly, the plurality of battery cells 2 may be connected in series and/or in parallel. As the plurality of battery cells 2 are connected in series and/or in parallel, a voltage may increase, or a value limit of a flowable current may increase. Accordingly, the capacity of the battery module 1 can increase.

The protruding busbar holder pin 3311 may be disposed to pass through the sensing module body hole 3100 of the sensing module 31 and/or the communication module body hole 323 of the communication module 32. The protruding busbar holder pin 3311 passing through the sensing module body hole 3100 and/or the communication module body hole 323 may be fixed to the busbar holder fixing part 332. According to one or more embodiments, the protruding busbar holder pin 3311 may be inserted into a busbar holder fixing groove 3321 of the busbar holder fixing part 332. As the protruding busbar holder pin 3311 is inserted into the busbar holder fixing groove 3321, the sensing module 31 and/or the communication module 32 can be prevented from being separated from the busbar holder 33.

The busbar holder fixing part 332 may be disposed on (for example, in a +Z-axis direction of) the sensing module 31 and/or the communication module 32. According to one or more embodiments, the busbar holder fixing part 332 may be disposed on the communication module 32 and coupled to the protruding busbar holder portion 331.

An inflow prevention member 34 (see FIG. 7) may be disposed on the sensing module body 310. The inflow prevention member 34 may be disposed between the sensing module 31 and the communication module 32. According to one or more embodiments, the inflow prevention member 34 may be disposed on the sensing module body 310 to surround the sensing pad portion 312 and the communication pad portion 321. As the inflow prevention member 34 is disposed to surround the sensing pad portion 312 and the communication pad portion 321, foreign matter such as water can be prevented from being introduced to the sensing pad portion 312 and the communication pad portion 321.

In FIG. 7, it is illustrated that one inflow prevention member 34 is disposed to surround the sensing pad portion 312 and the communication pad portion 321, but an example of the inflow prevention member 34 is not limited thereto. The inflow prevention member 34 may be disposed on each terminal (for example, a concave sensing pad portion 3121 or a protruding communication pad portion 3211 of FIG. 9, or a protruding sensing pad portion 3124 or a concave communication pad portion 3216 of FIG. 15) in contact with the sensing pad portion 312 and the communication pad portion 321 to surround an individual terminal.

As described above, the sensing module 31 and/or the communication module 32 may be disposed on the busbar holder 33 and fixed to the busbar holder 33 by the protruding busbar holder portion 331 and/or the busbar holder fixing part 332.

FIG. 9 is a cross-sectional view illustrating a state in which a sensing module is in contact with a communication module according to one or more embodiments of the present disclosure, and FIG. 10 is a cross-sectional view illustrating a state in which the sensing module is spaced apart from the communication module according to one or more embodiments of the present disclosure. FIG. 11 is a cross-sectional view illustrating a state in which a sensing module is spaced apart from a communication module according to another embodiment of the present disclosure, and FIGS. 12 to 14 are plan views each illustrating a layout of a sensing pad portion of a sensing module and a communication pad portion of a communication module according to one or more embodiments of the present disclosure sensing module.

A sensing module 31, a sensing module body 310, a sensing pad portion 312, a sensing line 3122, a communication module 32, a communication module body 320, and a communication pad portion 321 illustrated in FIGS. 9 to 14 are the same as the sensing module 31, the sensing module body 310, the sensing pad portion 312, the sensing line 3122, the communication module 32, the communication module body 320, and the communication pad portion 321 illustrated in FIGS. 1 to 8. Accordingly, description of the same components may be omitted.

Referring to FIGS. 9 and 10, the sensing pad portion 312 of the sensing module 31 and the communication pad portion 321 of the communication module 32 can be seen.

As the sensing pad portion 312 and the communication pad portion 321 are not implemented as connectors, and the sensing module 31 and the communication module 32 are disposed to overlap each other, the sensing pad portion 312 and the communication pad portion 321 may be in contact with and electrically connected to each other.

As described above, as the sensing pad portion 312 and the communication pad portion 321 overlap and are electrically connected, an additional connector structure is not needed. As the connector structure is not needed, a volume of a space needed for connecting the sensing module 31 and the communication module 32 may decrease, and a degree of integration of a circuit may decrease, thereby preventing a bottleneck phenomenon and lowering difficulty in a circuit design.

In addition, as the sensing module 31 provided as an FPCB does not need a connector structure, the sensing module 31 does not need to be cut for connection with a connector. Accordingly, a process of manufacturing the sensing module 31 can be simplified, a time for manufacturing the sensing module 31 can decrease, and a cost for the sensing module 31 can decrease.

When the connector structure is implemented on the sensing module 31 and/or the communication module 32, a worker should pay close attention during detaching or attaching the connector, and a possibility of damage to the sensing module 31 and/or the communication module 32 is great. As the connector structure is not needed, the communication module 32 may be easily attached to or detached from the sensing module 31. In addition, a process of separating the communication module 32 from the sensing module 31 can be simplified greatly, and a difficulty in the separating process can decrease.

Referring to FIGS. 9 and 10, the sensing line 3122 may be disposed in the sensing module body 310 of the sensing module 31. According to one or more embodiments, the sensing line 3122 may be disposed in the sensing module body 310.

The sensing line 3122 may be connected to the sensing pad portion 312.

The sensing pad portion 312 may include a concave sensing pad portion 3121 concavely formed in the sensing module body 310. The concave sensing pad portion 3121 may be provided as a groove concavely formed downward (for example, in a -Z-axis direction) from an upper side (for example, in a +Z-axis direction) of the sensing module body 310.

A sensing plate 3123 may be disposed on the concave sensing pad portion 3121. According to one or more embodiments, the sensing plate 3123 may be disposed on (for example, in a +Z-axis direction of) the sensing line 3122 and electrically connected to the sensing line 3122 and transmit an electrical signal to the sensing line 3122. The sensing plate 3123 may be in contact with the communication module 32. According to one or more embodiments, the sensing plate 3123 may be in contact with and electrically connected to the communication pad portion 321 of the communication module 32. The sensing plate 3123 may include a highly conductive material such as gold, silver, and copper. As the sensing line 3122 and the communication module 32 are connected through the sensing plate 3123 without being directly connected thereto, the sensing plate 3123 can protect the sensing line 3122.

The communication pad portion 321 may be disposed in the concave sensing pad portion 3121. According to one or more embodiments, the communication pad portion 321 may be inserted into the concave sensing pad portion 3121.

A communication line 3212 may be disposed in the communication module body 320. According to one or more embodiments, the communication line 3212 may be disposed in the communication module body 320. The communication line 3212 may be connected to the communication pad portion 321 and may transmit an electrical signal to the communication pad portion 321. According to one or more embodiments, a signal transmitted to the communication pad portion 321 through the sensing pad portion 312 may be transmitted to a communication module element 322 (see FIG. 7) of the communication module 32 through the communication line 3212.

The communication pad portion 321 may include a protruding communication pad portion 3211 protruding from the communication module body 320. The protruding communication pad portion 3211 may protrude downward (for example, in a -Z-axis direction) from an upper side (for example, in a +Z-axis direction) of the communication module body 320.

The protruding communication pad portion 3211 may be inserted into and come into contact with the concave sensing pad portion 3121. As the protruding communication pad portion 3211 is inserted into and comes into contact with the concave sensing pad portion 3121, the protruding communication pad portion 3211 and the concave sensing pad portion 3121 may be electrically connected to each other. Accordingly, the sensing module 31 and the communication module 32 may be electrically connected.

The protruding communication pad portion 3211 may be connected to the communication line 3212, and a communication solder 3213 may be disposed under (for example, in a -Z-axis direction of) the communication line 3212.

The communication solder 3213 may be a solder and be disposed in a manufacturing process. The communication solder 3213 may electrically connect the communication line 3212 and the communication pad 3214 and fix the communication pad 3214.

The communication pad 3214 may be disposed under (for example, in a -Z-axis direction of) the communication solder 3213 and electrically connected to the communication solder 3213. The communication pad 3214 may be electrically connected to the sensing line 3122. The communication pad 3214 may be formed of a highly conductive conductor.

A communication plate 3215 may be disposed under (for example, in a -Z-axis direction of) the communication pad 3214 and electrically connected to the communication pad 3214. As the communication pad 3214 is connected to the sensing module 31 through the communication plate 3215 without being directly connected thereto, the communication plate 3215 may protect the communication pad 3214. The communication plate 3215 may be formed of a highly conductive conductor such as gold, silver, and copper.

Referring to FIG. 11, it can be seen that a shape of a concave sensing pad portion 3121 and a shape of the protruding communication pad portion 3211 are different from each other.

A cross-sectional area of a concave sensing pad portion 3121 and a protruding communication pad portion 3211 may increase in one direction. According to one or more embodiments, the cross-sectional area of the concave sensing pad portion 3121 perpendicular to a Z-axis direction may increase in a +Z-axis direction.

An inclination intersecting the Z-axis direction may be provided on a portion of the sensing module body 310 and a portion of a cross section of a sensing plate 3123 of the concave sensing pad portion 3121. According to one or more embodiments, a cross-sectional shape of the portion of the sensing module body 310 and the sensing plate 3123 of the concave sensing pad portion 3121 may be provided as a substantially trapezoidal shape.

An inclination intersecting the Z-axis direction may be formed on a portion of the communication module body 320 and a portion of a cross section of a communication pad 3214 and a communication plate 3215 of the protruding communication pad portion 3211. According to one or more embodiments, a cross-sectional shape of the portion of the communication module body 320, the communication pad 3214, and the communication plate 3215 of the protruding communication pad portion 3211 may be provided as a substantially trapezoidal shape.

As described above, as the cross-sectional shape is provided as the substantially trapezoidal shape, when the communication module 32 comes into contact with the sensing module 31, contact between the sensing pad portion 312 and the communication pad portion 321 may be guided.

Referring to FIGS. 9 to 11, an area of the concave sensing pad portion 3121 may be formed to be greater than an area of the protruding communication pad portion 3211. According to one or more embodiments, the area of the concave sensing pad portion 3121 cut in a direction perpendicular to the Z-axis direction may be formed to be greater than the area of the protruding communication pad portion 3211.

As described above, as the area of the concave sensing pad portion 3121 is formed to be greater than the area of the protruding communication pad portion 3211, even when the communication module 32 is not disposed at an accurate location desired by a designer, the sensing module 31 and the communication module 32 may be electrically connected. An example thereof will be described with reference FIGS. 12 to 14.

Referring to FIG. 12, it can be seen that the sensing module 31 and/or the communication module 32 are accurately disposed at designed locations so that a protruding communication pad portion 3211 is disposed at a center of a concave sensing pad portion 3121 of the sensing module 31. Accordingly, it can be seen that a communication plate 3215 of the protruding communication pad portion 3211 is disposed at a center of a sensing plate 3123 of the concave sensing pad portion 3121.

Referring to FIG. 13, it can be seen that the sensing module 31 and/or the communication module 32 is disposed to be biased in one direction (for example, a -X-axis direction) without being accurately disposed at a designed location so that a protruding communication pad portion 3211 is disposed in an end portion of one side (for example, in a -X-axis direction) of a concave sensing pad portion 3121. Accordingly, it can be seen that a communication plate 3215 of the protruding communication pad portion 3211 is disposed in an end portion of one side (for example, in the -X-axis direction) of a sensing plate 3123 of the concave sensing pad portion 3121.

Referring to FIG. 14, it can be seen that the sensing module 31 and/or the communication module 32 is disposed to be biased in one direction (for example, in a -Y-axis direction) without being accurately disposed at a designed location so that a protruding communication pad portion 3211 is disposed in an end portion of one side (for example, in a -Y-axis direction) of a concave sensing pad portion 3121. Accordingly, it can be seen that a communication plate 3215 of the protruding communication pad portion 3211 is disposed in an end portion of one side (for example, in a -Y-axis direction) of a sensing plate 3123 of the concave sensing pad portion 3121.

As in FIGS. 12 to 14, as an area of the concave sensing pad portion 3121 is formed to be greater than an area of the protruding communication pad portion 3211, even when the sensing module 31 and/or the communication module 32 is not accurately disposed at a designed location, the sensing module 31 and the communication module 32 may be electrically connected. Accordingly, preciseness needed for assembling a management module 3 can be lowered, and a manufacturing (assembling) time can be reduced.

The embodiment, in which a sensing pad portion 312 protrudes from a sensing module body 310 and a communication pad portion 321 is concavely formed in a communication module body 320, is illustrated in FIGS. 15 and 16.

The sensing pad portion 312 may include a protruding sensing pad portion 3124, and the communication pad portion 321 may include a concave communication pad portion 3216.

The protruding sensing pad portion 3124 may be inserted into and come into contact with the concave communication pad portion 3216.

A sensing line 3122 may be disposed in the sensing module body 310. According to one or more embodiments, the sensing line 3122 may be disposed in the sensing module body 310. The sensing line 3122 may be connected to the sensing pad portion 312 and transmit an electrical signal to the sensing pad portion 312.

The sensing pad portion 312 may include the protruding sensing pad portion 3124 formed to protrude from the sensing module body 310. The protruding sensing pad portion 3124 may protrude upward (for example, in a +Z-axis direction) from a lower side (for example, in a -Z-axis direction) of the sensing module body 310.

The protruding sensing pad portion 3124 may be inserted into and come into contact with the concave communication pad portion 3216. As the protruding sensing pad portion 3124 is inserted into and comes into contact with the concave communication pad portion 3216, the protruding sensing pad portion 3124 and the concave communication pad portion 3216 may be electrically connected. Accordingly, the sensing module 31 and the communication module 32 may be electrically connected.

The protruding sensing pad portion 3124 may be connected to the sensing line 3122, and the protruding sensing solder 3124-1 may be disposed on (for example, in a +Z-axis direction of) the sensing line 3122.

The protruding sensing solder 3124-1 may be a solder and be disposed in a manufacturing process. The protruding sensing solder 3124-1 may electrically connect the sensing line 3122 and the protruding sensing pad 3124-2 and fix the protruding sensing pad 3124-2.

The protruding sensing pad 3124-2 may be disposed on (for example, in a +Z-axis direction of) the protruding sensing solder 3124-1 and electrically connected to the protruding sensing solder 3124-1. The protruding sensing pad 3124-2 may be electrically connected to a communication line 3212. The protruding sensing pad 3124-2 may be formed of a highly conductive conductor.

The protruding sensing plate 3124-3 may be disposed on (for example, in a +Z-axis direction of) the protruding sensing pad 3124-2 and electrically connected to the protruding sensing pad 3124-2. As the protruding sensing pad 3124-2 is connected to the communication module 32 through the protruding sensing plate 3124-3 without being directly connected thereto, the protruding sensing plate 3124-3 may protect the protruding sensing pad 3124-2. The protruding sensing plate 3124-3 may be formed of a highly conductive conductor such as gold, silver, and copper.

The concave communication pad portion 3216 may include a concave communication plate 3216-1.

The concave communication plate 3216-1 may be disposed in the concave communication pad portion 3216. According to one or more embodiments, the concave communication plate 3216-1 may be disposed under (for example, in a -Z-axis direction of) the communication line 3212 and electrically connected to the communication line 3212 and may transmit an electrical signal to the communication line 3212. The concave communication plate 3216-1 may be in contact with the sensing module 31. According to one or more embodiments, the concave communication plate 3216-1 may be in contact with and electrically connected to the sensing pad portion 312 of the sensing module 31. The concave communication plate 3216-1 may include a highly conductive material such as gold, silver, and copper. As the communication line 3212 is connected to the sensing module 31 through the concave communication plate 3216-1 without being directly connected thereto, the concave communication plate 3216-1 may protect the communication line 3212.

An area of the concave communication pad portion 3216 may be formed to be greater than an area of the protruding sensing pad portion 3124. According to one or more embodiments, the area of the concave communication pad portion 3216 cut in a direction perpendicular to a Z-axis direction may be formed to be greater than the area of the protruding sensing pad portion 3124.

As described above, as the area of the concave communication pad portion 3216 is formed to be greater than the area of the protruding sensing pad portion 3124, even when the sensing module 31 and/or the communication module 32 is not accurately disposed at a designed location, the sensing module 31 and the communication module 32 may be electrically connected. Accordingly, preciseness needed for assembling a management module 3 can be lowered, and a manufacturing (assembling) time can be reduced.

Referring to FIG. 16, advantages corresponding to the advantages of the present disclosure described with respect to FIGS. 12 to 14 can be seen.

FIG. 17 is a cross-sectional view illustrating a state in which a sensing module is spaced apart from a communication module according to yet another embodiment of the present disclosure.

The embodiment illustrated in FIG. 17 is similar to the embodiment illustrated in FIGS. 10 and 11. The embodiment in which a contact guide part 350 is disposed to be adjacent to a sensing pad portion 312 and a communication pad portion 321 is illustrated in FIG. 17.

Referring to FIG. 17, the contact guide part 350 may be disposed on a sensing module body 310 and a communication module body 320 and may guide contact between the sensing pad portion 312 and the communication pad portion 321.

A plurality of guide members 351 may be disposed on the sensing module body 310 and/or the communication module body 320, and the attraction may act therebetween. As the attraction acts between the guide members 351, a sensing module 31 and a communication module 32 may come into contact with each other due to the attraction between the plurality of guide members 351 according to desired arrangement of a designer when the sensing module 31 comes into contact with the communication module 32.

In addition, as the attraction between the plurality of guide members 351 acts even after the sensing module 31 and the communication module 32 are in contact with each other, the sensing module 31 and the communication module 32 can be fixed.

The adhesive member 352 may be disposed on the sensing module body 310 and/or the communication module body 320 and may fix the guide member 351. The adhesive member 352 may be provided as any one of various members such as an adhesive and an adhesive tape.

Accordingly, description of the same components may be omitted.

Referring to FIGS. 18 to 20, it can be seen that the sensing module body 310 and the communication module body 320 are fixed by the protruding busbar holder portion 331 and the busbar holder fixing part 332.

The protruding busbar holder portion 331 may include a protruding busbar holder pin 3311 and a protruding busbar holder protrusion 3312.

The protruding busbar holder pin 3311 and the protruding busbar holder protrusion 3312 may be disposed to protrude upward (for example, in a +Z-axis direction) from the busbar holder body 330.

The protruding busbar holder pin 3311 may pass through a sensing module body hole 3100 of the sensing module body 310, a communication module body hole 323 of the communication module body 320, and an elastic member 333 and may be inserted into the busbar holder fixing part 332. According to one or more embodiments, the protruding busbar holder pin 3311 may be inserted into a busbar holder fixing groove 3321 formed in a concave shape in the busbar holder fixing part 332.

The protruding busbar holder protrusion 3312 may be coupled to the busbar holder fixing part 332.

The elastic member 333 may be disposed between the sensing module body 310 and the protruding busbar holder portion 331 and/or between the communication module body 320 and the busbar holder fixing part 332. The elastic member 333 may be formed of an elastic material such as rubber.

As the elastic member 333 is disposed between the sensing module body 310 and the protruding busbar holder portion 331 and/or between the communication module body 320 and the busbar holder fixing part 332, damage to the sensing module body 310 and/or the communication module body 320 can be prevented. In addition, as the elastic member 333 presses the sensing module body 310 and the communication module body 320 such that the sensing module body 310 and the communication module body 320 come close to each other, contact between a sensing pad portion 312 of the sensing module body 310 and a communication pad portion 321 of the communication module body 320 can be maintained.

Secondary batteries are widely used for driving or energy storage in not only small apparatuses such as portable electronic devices but also medium-to-large apparatuses such as electric vehicles or energy storage systems (ESSs).
